Aortic Science Made Simple - Exercise May Not Be a No-Go for Aortic Dissection Survivors.
🧬🫀 NEW BLOG ALERT: AORTIC SCIENCE MADE EASY!
Research can be fascinating…but let’s face it, sometimes reading a published medical study can feel like you need a medical degree just to get through the first paragraph! 🤯
That’s exactly why we created Aortic Science Made Easy—and our newest medical blogger, Aditi Darodkar, is kicking things off with a topic MANY survivors ask about:
đź’Ş EXERCISE AFTER AORTIC DISSECTION.
Her first article, “Exercise May Not Be a No-Go for Aortic Dissection Survivors,” breaks down recently published research into language our community can actually understand.
đź‘€ Could the conversation around exercise after aortic dissection be changing?
Come find out!
đź«€ Science doesn't have to be complicated to be powerful.

Title: Exercise may not be a no-go for aortic dissection survivors
For years, aortic dissection survivors were told to completely avoid exercise after surgery.
The concern was understandable: physical exertion can temporarily raise blood pressure, and elevated systolic blood pressure is associated with catastrophic complications in people with aortic disease. However, on July 2nd, 2026, University of Texas (UT) Health Science Center at Houston released a study challenging this convention.
In this randomized control trial, 93 patients were divided into two groups. The control group received a pamphlet reflecting the current standard of post-operative exercise care, which included “a recommended exercise amount of 30 minutes per day, aerobic activities for about 150 minutes a week, and then some guidance on what not to do like lift heavy weights,” said Dr. Siddharth Prakash, a cardiologist and professor of medical genetics at UT Health Science Center at Houston. By contrast, the experimental group received in-person training for a circuit of six exercises at a cardiac rehabilitation facility. Participants were instructed not to hold their breath during exertion and were given feedback on proper exercise techniques.
The exercise circuit was curated to incorporate “different categories [such as] bicep curls, which is a resistance exercise; running on a treadmill, which is an aerobic activity; and hand grips which reflect a different set of muscle groups that people usually use,” noted Prakash. Additionally, this circuit was made to be “modifiable so that anyone could do them no matter what their level of physical activity was” and accessible so “that [the exercise circuit] could be done without any fancy equipment, either in a home gym or at home completely with equipment you can buy at the store,” continued Prakash. The experimental group also received 12 months of virtual follow-up visits, unlike the control group.
Three main outcomes were evaluated: blood pressure, safety and mental health.
24-hour ambulatory blood pressure was collected before and after the study. Results showed that “ although [the data did not have] statistical significance, the distribution of the systolic blood pressure readings [revealed that] less people had high blood pressure at the end of the study,” said Prakash, who believes that a larger clinical trial could produce statistically significant results. “Exercise paradoxically increases blood pressure during activity but [decreases] during the subsequent rest period, [resulting in] lower blood pressure on average.”
The second, and perhaps the most important result, focused on safety. Among the participants who were at least 3 months post-Type A or Type B aortic dissection, “nobody had a rupture and nobody needed emergency aortic surgery in the 12 months of follow up,” noted Prakash.
Finally, the study did not find a significant change in participants’ mental health. According to Prakash, this may have been because the study enrolled a highly motivated group of participants who were generally doing well at the start of the trial. In prospective studies, he hopes to include patients experiencing greater mental health challenges at baseline to determine whether regular physical activity could have a more substantial impact. Other future directions include making this a “100% home based trial, using virtual coaching and collecting data using wearable [technology so that researchers can] check in on [participants] remotely,” stated Prakash.
Ultimately, this study demonstrated that exercise under observation can be safe for aortic dissection survivors. Prakash believes that individuals “ don't necessarily [have] to travel hundreds of miles to be observed in a hospital, but maybe engaging in a personal trainer or a physical therapist could be helpful.” The research team attributes the success of this trial in part to its coaching component, as participants reported that receiving “positive feedback [on their exercise methods] increased their confidence to go home and do the exercises.” And, follow-up visits allowed participants to discuss integration of exercises into their lives beyond the trial, helping them continue the circuit over time.
